This interval further includes: • 8m @ 4.7g/t Au from 154m to EOH. o 50*1m @ 1.3g/t Au from 122m in 25IWBRC0042 (ETW of 24m), including  28m @ 1.9g/t Au from 143m. This interval further includes: • 9m @ 2.1g/t Au from 145m, and • 7m @ 2.7g/t Au from 164m. *1: Down-hole width reported, as true width is uncertain, and further drilling is required to confirm the geometry of mineralisation. • The approximately 2,000m diamond drilling program is anticipated to be completed in four to six weeks, with results expected in December. • Preparations are also underway for a circa. 5,000m RC program at Arrakis across 200m spaced lines that will commence in November. • The recently completed A$13.5 million capital raising enables Yandal Resources to expand and accelerate exploration across the Ironstone-Well Barwidgee Gold Project, including the Arrakis discovery, New England Granite target area and Flushing Meadows deposit. ASX Announcement 13 October 2025 yandalresources.com.au | ASX:YRL 2 For further information or to ask questions in relation to this announcement, please visit our Investor Hub at https://yandalresources.com.au/link/e958Ve Commenting on the new results, Yandal Resources’ Managing Director, Mr. Chris Oorschot, said: “Geological logging from previous intercepts indicate that a zone of intense silica alteration or micro-crystalline veining marks the eastern boundary of mineralisation, and while intense alteration and deformation were observed in these last three RC holes, particularly within 25IWBRC0044 and 25IWBRC0046, a comparison of alteration types and zonation suggests they finished before the targeted Arrakis structure. While it is disappointing that these final RC holes did not penetrate the targeted Arrakis structure, they provide a perfect pre-collar for diamond drilling, potentially enabling speedy access to oriented diamond core intercepting the Arrakis structure. Arrakis is the result of an exploration strategy that is centred on delivering large-scale discoveries. The Caladan target area and the discovery of Arrakis therein have progressed rapidly over the last three months. This progress has been made utilising broad 800m and 400m spaced drill lines that were applied to identify evidence of the broad mineralised system. There is plenty of work ahead, with early results suggesting an extensive mineralised system. Looking ahead, the team will focus on understanding the full extent of mineralisation over the coming months.” Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to report that the results from 25IWBRC0044, 25IWBRC0045, and 25IWBRC0046, part of the recently completed reverse circulation (RC) drilling program across the Arrakis Prospect, have been received. The RC drilling program included seven (7) RC holes for a total of 1,374m, across 400m and 800m spaced lines targeting mineralisation intercepted within recent air-core drilling that defines the more than 2.2km long mineralised Arrakis structure (see Figure 3). The RC program was designed to confirm the continuity and geometry of mineralisation within fresh rock below several significant air-core intercepts that occurred in either fully or partially weathered rock. RC holes 25IWBRC0044 and 25IWBRC0046 (see Figure 1) did not return significant intercepts. A geological review indicates that neither of the RC holes intercepted the targeted Arrakis mineralisation. Furthermore, the targeted Arrakis structure is likely to be intercepted if both holes are extended, with diamond core tails designed and scheduled for completion in the coming weeks. RC hole 25IWBRC0045 was drilled to test below an air-core intercept of 5m @ 0.7g/t from 112m to EOH in 25IWBAC0052, located 800m northwest of the 2.2km mineralised Arrakis trend. The RC hole has effectively tested below this intercept and returned only low-level gold anomalism within fresh rock. Logging indicates a broad zone of shearing was intercepted with intense chlorite alteration; however, the alteration styles associated with Arrakis mineralisation were not observed. yandalresources.com.au | ASX:YRL 3 The broadly spaced seven-hole RC program has successfully confirmed Arrakis as a new gold discovery and achieved its core aims of assessing mineralisation continuity into fresh rock and verifying the geometry of mineralisation on section. The results of this program demonstrate the potential for a mineralised system of regional significance. Diamond core drilling is scheduled to commence in the coming days and will include several re-entries of RC holes (diamond tails, see Figure 2) and several deeper diamond holes below recently reported intercepts (see ASX releases 22 September 2025 and 24 September 2025). In addition to this, RC drilling across 200m spaced lines is scheduled to commence in November to define the extent of mineralisation across the Arrakis discovery. The Arrakis Prospect is located within the Caladan target area (tenements E 53/1843, E 53/2304, E 53/2192 and E 53/1882), part of the broader Ironstone Well-Barwidgee Gold Project (see Figure 4), located 60km south of the Jundee mining complex (ASX: NST), and 18km north the recent Siona discovery, within the Yandal Greenstone Belt. Next Steps An approximately 2,000m diamond core program will commence in the coming days. The program will aim to complete several re-entries extending RC holes that ended within or adjacent to mineralisation. In addition to this, several new diamond holes from the surface will be completed to test below the recent intercepts from 25IWBRC0040 and 25IWBRC0042 (see Figure 2). A heritage survey clearing 100m spaced lines across the Arrakis Prospect is underway to provide significant capacity for closer spaced drilling across the Arrakis discovery. A 5,000m RC drilling program has been scheduled for November. This drilling will aim to complete drilling on 200m spaced lines across the 2.2km striking Arrakis trend, to delineate the extent of the mineralised system and begin to understand how gold mineralisation varies along strike and at depth. yandalresources.com.au | ASX:YRL 4 Figure 1: Cross-section showing all RC drilling results from 25IWBRC0046, with a simple preliminary interpretation of geology.

The following Table and Sections are provided to ensure compliance with the JORC Code (2012 edition) requirements for the reporting of Exploration Results. Section 1 Sampling Techniques and Data Criteria JORC Code explanation Commentary Sampling techniques Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Yandal Resources has completed RC drilling across several 400m and 800m spaced lines across the Arrakis Prospect, targeting fresh rock mineralisation below recently reported air-core intercepts. The drilling involved 139mm face sampling bit down to between 162m and 288m. Holes were drilled at an angle of -60° to the southwest. • Yandal Resources (YRL) RC drilling samples were collected via a rig-mounted static cone splitter, splitting approximately 12.5% of the total sample volume. Two splits are collected for each metre: a primary and duplicate sample. The primary 1m samples are then sent to a lab for further analysis. The duplicate samples are retained on-site unless they are submitted as routine duplicates. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • For YRL RC drilling, the cone splitter is regularly cleaned and inspected. The 1m bulk samples are laid out in drill order. These bulk samples are regularly inspected for contamination, and the volume of the bulk sample is monitored. These bulk samples are retained until all results are received and may be used to collect additional field duplicates to verify lab results, logged geology or any other form of analysis. If the bulk sample appears visually low in volume or weight, this is recorded with the sample details. The same applies to damp or wet samples. • Two splits are collected for each drilled metre: a primary and a secondary sample. The Secondary sample is retained on-site and may be used to collect additional field duplicates to verify lab results, logged geology or any other form of analysis Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual • RC drilling was used to obtain 1m samples from which a portion, between 1-5kg in weight, was dispatched to Aurum Laboratories Pty Ltd: • At the lab, samples were crushed and pulverised to produce a 50g charge for fire assay with an AAS (atomic absorption spectroscopy) finish for gold determination with a 0.01ppm detection limit. ASX Announcement 13 October 2025 Page 13 Criteria JORC Code explanation Commentary commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Drilling techniques Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). • For YRL RC drilling, a 139mm diameter face sampling bit and hammer was used. Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • For YRL holes, RC drilling recoveries are visually assessed by the supervising geologist, and any low-volume or weight samples are recorded, along with any damp or wet samples. Drill depths are routinely verified at the completion of each drill rod (every 6m). The cone splitter is checked for each drill site to ensure it is completely upright and level. Sample collection from the splitter by drilling off-siders is monitored for any inefficiencies. • Within the limited drilling completed, there appears to be no correlation between sample recovery and sample grade. Logging Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. • For YRL drilling, all RC holes have been logged in full by a qualified and experienced geologist. RC chips and fines from each 1m interval drilled are inspected and logged for colour, weathering, lithology, deformation, veining and sulphide species. All 1m samples are sieved and retained in labelled and annotated chip trays. Chip trays are transported to Perth for long- term storage and are available for review. The quality of logging information is considered sufficient to support Mineral Resource Estimation studies. • Data captured through geological logging by a geologist is qualitative in nature. • In addition to geological logging, the magnetic susceptibility of each interval is measured using a KT-10 magnetic susceptibility metre, with a sensitivity of 1x10-6 SI Units. Magnetic susceptibility readings are quantitative in nature. Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken. • YRL RC drilling utilised a rig-mounted cone splitter installed directly below and in line with the rig-mounted cyclone. Two 1-3kg sub-samples are collected into calico bags labelled with a unique alpha-numeric ID. A majority of the samples collected were dry; if samples were damp or wet, this was noted in the sample records. • For all YRL RC drilling, samples are dried at 100°C to constant mass, crushed to <10mm and ASX Announcement 13 October 2025 Page 14 Criteria JORC Code explanation Commentary If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. pulverised to nominally 85%, passing 75µm. • Field duplicates were collected at an initial rate of 1 duplicate for every 50 samples collected. • Standards and blanks (certified reference material or CRM) were routinely inserted into the sample sequence at a rate of 1 CRM for every 20 samples collected. • For labs used by YRL, internal lab quality control measures include lab duplicates and the insertion of lab standards and blanks. • Sample sizes are appropriate given the fine-to-medium-grained nature of the sampled material. Quality of assay data and laboratory tests The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • For YRL RC drilling, samples were assayed at the following labs using the following methods: o Aurum Laboratories in Beckenham, Western Australia, assayed using a 50g fire assay with AAS (atomic absorption spectroscopy) finish for gold analysis with a 0.01ppm detection limit. • Magnetic susceptibility measurements were taken every meter using a KT-10 V2 instrument with a sensitivity of 1x10-6 SI Units. • YRL QAQC field protocols include the insertion of commercially prepared certified reference material (CRM) and blank material at a rate of approximately 1 CRM/blank for every 20 samples collected. CRMs used are unidentifiable by the lab when received. QAQC performance is monitored upon receipt of each batch of results and re-assessed once all samples for a program are received. • Laboratory QA/QC protocols involve inserting internal lab standards using CRMs, blanks, repeat analysis of pulps and screen tests (the percentage of pulverised material passing 75µm mesh). Laboratory QAQC results are reported with each batch. Laboratory QAQC performance is monitored upon receipt of each batch of results and assessed again once all samples for a program are received. Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. • Significant intercepts from YRL RC drilling are verified by YRL geologists through the visual inspection of chips, reviewing the spatial location of mineralisation relative to previous intercepts, and in the case of high-grade gold intercepts, the panning of drill fines to visually confirm gold in samples. • No twinned holes have been completed across the Caladan or Irulan target area. ASX Announcement 13 October 2025 Page 15 Criteria JORC Code explanation Commentary Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. • For YRL RC drilling, primary sampling and logging data are captured directly into the MX deposit application and uploaded directly to the cloud-hosted MX Deposit database. • The first assay result for each sample is used for the reporting of significant intercepts, and no adjustments have been made to the assay data. Location of data points Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. • All drill collar locations were initially pegged and surveyed using a handheld Garmin GPS, which was accurate to within +/- 5m. RLs are determined using a detailed surface DTM. • All RC holes were downhole surveyed using a gyroscopic survey tool, producing azimuth readings relative to true north that are then converted to UTM MGA94 Zone 51s. Readings are collected at a maximum spacing of 30m downhole or better. • All spatial data presente
